This must be for the Vault (multisig) product, which Unchained charges $250/yr for. Their original service is still free if you auto-withdraw, which is the only reason many went with Swan to begin with. They're bitcoin only and they encourage self-custody. Where did you clip that from?
Yeah they are trying to sweep all customers into their swan vault product and charge you 3 basis points for holding your UTXOs for you. Guess it make sense I know most savvy bitcoiners wait to hit a certain UTXO threshold before withdrawing
Swan banned me from withdrawing for some reason two years ago. I forget the details. I did finally manage to free my bitcoin. Then they stopped accepting NY resident accounts. A few months ago they sent me a friendly note saying that I could still buy bitcoin, but withdrawals are barred in my state.
I guess my account with zero balance still exists, but I will never use them again.
